作为高等教育网络学习中心的帕亚米·努尔大学应该采取措施来建立质量管理系统.并且改革或改变教育服务的机构.在2005~2006年帕亚米·努尔大学中心组织使用EFQM模型作了自我评估,目的是为了建立质量管理系统.为了重新评估该组织,为了通过比较连续两年的成绩来监控该组织发挥作用的效果、为了检测去年进行的第一次试验结果的不足的改进程度,我们又进行了第二次试验,题目相同,试验方法稍作更改.试验的主要目的是为了重新评估该组织通过使用EFQM模型后如何提高了自己的作用并比较这两次试验的结果.本实验除了进行文献搜索以外,还进行了实地调查.  相似文献

Nascent academic entrepreneurs need to acquire entrepreneurial competencies to create successful spin-off ventures. In this article, we examine difficulties in this pursuit prior to venture formation and offer a systematic classification of inhibitors. We confirm, combine, and extend two previously identified inhibiting mechanisms into a relational inhibitor category, classify additional structural and cultural-cognitive inhibitors, and highlight how these inhibitors exist both at the individual and the organizational level. We then advance theoretical understanding of the interrelated, multilevel functions of inhibitors on the development of entrepreneurial competencies, and offer policy insights on how universities can mitigate their effects.  相似文献

Mouth rinsing using a carbohydrate (CHO) solution has been suggested to improve physical performance in fasting participants. This study examined the effects of CHO mouth rinsing during Ramadan fasting on running time to exhaustion and on peak treadmill speed (Vpeak). In a counterbalanced crossover design, 18 sub-elite male runners (Age: 21?±?2 years, Weight: 68.1?±?5.7?kg, VO2max: 55.4?±?4.8?ml/kg/min) who observed Ramadan completed a familiarization trial and three experimental trials. The three trials included rinsing and expectorating a 25?mL bolus of either a 7.5% sucrose solution (CHO), a flavour and taste matched placebo solution (PLA) for 10?s, or no rinse (CON). The treatments were performed prior to an incremental treadmill test to exhaustion. Three-day dietary and exercise records were obtained on two occasions and analysed. Anthropometric characteristics were obtained and recorded for all participants. A main effect for mouth rinse on peak velocity (Vpeak) (CHO: 17.6?±?1.5?km/h; PLA: 17.1?±?1.4?km/h; CON: 16.7?±?1.2?km/h; P?ηp2?=?0.49) and time to exhaustion (CHO: 1282.0?±?121.3?s; PLA: 1258.1?±?113.4?s; CON: 1228.7?±?98.5?s; P?=?.002, ηp2?=?0.41) was detected, with CHO significantly higher than PLA (P?P?P?>?.05). Energy availability from dietary analysis, body weight, and fat-free mass did not change during the last two weeks of Ramadan (P?>?.05). This study concludes that carbohydrate mouth rinsing improves running time to exhaustion and peak treadmill speed under Ramadan fasting conditions.  相似文献

Background: Correct identification of misconceptions is an important first step in order to gain an understanding of student learning. More recently, four-tier multiple choice tests have been found to be effective in assessing misconceptions.

Purpose: The purposes of this study are (1) to develop and validate a four-tier misconception test to assess the misconceptions of pre-service physics teachers (PSPTs) about geometrical optics, and (2) to assess and identify PSPTs’ misconceptions about geometrical optics.

Sample: The Four-Tier Geometrical Optics Test (FTGOT) was developed based on findings from the interviews (n = 16), open-ended testing (n = 52), pilot testing (n = 53) and administered to 243 PSPTs from 12 state universities in Turkey.

Design and Methods: The first phase of the study was the development of a four-tier test. In the second phase of this study, a cross-sectional survey design was used.

Results: Validity of the FTGOT scores was established by means of some qualitative and quantitative methods. These are: (1) content and face validations by six experts; (2) Positive correlations between the PSPTs’ correct scores considering only first tiers of the FTGOT and their confidence score for this tier (r = .194) and between correct scores considering first and third tiers and confidence scores for both of those tiers (r = .218) were found as evidences for construct validity. (3) False positive (3.5%), false negative (3.3%) and lack of knowledge (5.1%) percentages were found to be less than 10% as an evidence for content validity of the test scores. (4) Explanatory factor analysis conducted over correct and misconception scores yielded meaningful factors for the correct scores as an evidence for construct validity. Additionally, the Cronbach alpha coefficients were calculated for correct scores (r = 0.59) and misconception scores (r = 0.42) to establish the reliability of the test scores. Six misconceptions about geometrical optics, which were held by more than 10% of the PSPTs, were identified and considered to be significant.

Conclusions: The results from the present investigation demonstrate that the FTGOT is a valid and reliable instrument in assessing misconceptions in geometrical optics.  相似文献

Emotional intelligence is an important area of psychology, which has gained acceptance in almost every academic discipline. It also seems to influence the various academic activities undertaken by students. This article, which is part of a larger study, reviews the literature on emotional intelligence, and its relationship with the academic and nonacademic characteristics of students with an emphasis on the significance of this relationship. This review shows that emotional intelligence of students is a key element for them while handling a stressful situation. It also illustrates that emotional intelligence can be supportive in managing library anxiety among students leading to better academic performance. This article will assist the academic librarians to recognize the role of emotional intelligence in library-related activities of the patrons. It is recommended that future research should give more attention to this area.  相似文献
